Cerebral vascular malformation, not always bleeding tendency, some may also be due to interference with the normal blood circulation in the skull, thus causing ischemic nature of the lesion, must depend on the specific circumstances, because cerebral vascular malformation, this classification is very much, including aneurysm, arteriovenous malformation, cavernous hemangioma, arteriovenous fistula and so on. For this disease as a whole, hemorrhage can only be said to be caused by increased blood pressure leading to rupture of the vessel wall, some may also produce compression of the surrounding brain tissue to form a placeholder effect, but also may lead to other blood vessel occlusion resulting in cerebral infarction, cerebral infarction, and a series of changes in the condition of the cerebral infarction. For cerebrovascular malformations, it is important to detect them at an early stage and intervene early, including interventional embolization or craniotomy, which can effectively reduce the secondary damage brought by the later stage.
